Migration From Thunderbird 2.0 To Thunderbird 3.0
Upon release of Thunderbird 3.0, next big changes were made.
- Gloda(Global Search and Indexer) is enabled by default.
- Auto-sync of IMAP folders is enabled by default for all IMAP accounts.
- Per folder "offline use" setting of all IMAP folders is set to "offline use=ON" by default upon migration(first use of Tb 3.0.x).
- View of folder pane is forced to "Smart Folders" view even though "All Folders" is Tb 2 user's ordinal choice in his daily use.
- Tb 2's "Account Wizard" and Tb3.0beta's "Account Wizard for Gmail IMAP" is removed before official release of Tb 3.0.0.
But spec of above changes, required settings for above changes is not so well documented yet. This Migration Guide is to avoid confusions by sysem management people upon upgrade from Tb 2.0.x to Tb 3.0.x due to above big/important/drastic changes by Tb 3.0.x.

Account definition by autoconfig
As only "autoconfig" is availabe for account definition, setups for autoconfig should be carefully done, in order to avoid user's confusions due to unexpected behaior of autoconfig or failure during autoconfig, if account definition by user himself is permitted.
"Smart Folders" view at folder pane
View of folder pane is changed to "Smart Folders" by default. As ordinal use is "All Folders", change to "All Folders" should be recommended to users, in order to unwanted questions to Help Center.
